Sonar Echo Analysis.

Abstract

Pulse mode sonar operation is analyzed under the assumption that the scattering object Gamma lies in the far fields of both the transmitter and the receiver. It is shown that, in this approximation, the sonar signal is a plane wave s(x times Theta(0)-t) near Gamma, where Theta(0) is a unit vector directed from the transmitter towar Gamma and similarity the echo is a plane wave e(x times Theta (0)-t) near the receiver, where Theta is a unit vector directed from Gamma toward the receiver.
